Starseed was the Superstar Daycare's receptionist at the Pizza Plex. 

She's also responsible for scheduling dates made by the parents to bring their children. 

She would often partner up with Moon whenever naptime comes around and would make the ceiling light up with stars that illuminate from her hands for those who are scared of the dark with a gentle color hue. (when in reality, the star stickers on the ceiling only lights up to Starseed's command but become dark when the lights turn on)

She glides around the Daycare while being hooked to the line to observe and inform Sun if the children out of his sight are either misbehaving or if property is destroyed. 

Although....she was attacked by Moon while protecting a child he was about to hurt....and he nearly kills her by dropping her from lethal height but survived....but....after the Daycare shut down....she ran away out of fear because of Moon leaving Sun to lose his mind. 

She was never seen again.
